Welcome to Project Bublik

Project Bublik is the story of an ongoing development process between Alexander Bublik and Diadem. It's a working snapshot of the specs, feel, and construction being refined toward his eventual signature frame. With dozens of prototypes and thousands of design decisions, Project Bublik is a work-in-progress that players around the world get to participate in. 

Most signature rackets are launched as finished products. We did the opposite. Project Bublik is a checkpoint along the way rather than a final conclusion.

Diadem and Bublik are building his frame the way he plays: entertaining, unconventional, and with a refusal to settle. Project Bublik captures that process mid-stride with current specs, current tuning, current feel. Never stagnant, always moving.

"Tennis, for me, has always been about doing things my way. So when I started working with Diadem to build my perfect racket, I wanted the same thing: something built exactly for how I play, with no compromises. Project Bublik is the first step of that journey. It's a frame we've developed together, tuned to my specs, my feel, my game. It's not finished yet. We're still refining, still pushing, still chasing perfection. But I wanted you to be part of that process."

Project Bublik 100 has been great will get to use it in a match in a few week and see how I do with it. If nothing else, it looks amazing. Used Solstice Black 17 at 56lb on both mains and crosses.

Self-esteem booster

I get a lot of compliments on and off the court with this racket. Even my crush complimented me on my racket. It is a great feeling racket too. Made the switch from the Wilson Ultra Pro 99 to the Bublik 98, and will stay that way for a long way.

Spin monster

I'm getting back into tennis after a twelve-year absence. I'm an all-court 4.0-4.5, one-hand backhand and prefer to finish points at the net if given the chance. My previous racquet of choice was very old-school, thin beam and head light and the same stiffness rating as the Bublik. The Bublik racquet is really fun to hit with and rewards good technique with both spin and power. I found that if I stepped into my backhands with proper technique the Bublik produed a heavy ball with lots of spin, something I can't do with my previous racquet. The sweet spot is fine but off-center shots produce a bit of vibration, even with a good string dampener. In a way, it reminds me to use good technique but I worry about wrist and elbow problems down the line, so far, so good. I'm using Diadem's multifilliment strung at mid-tension (which I believe is about 55 lbs) One thing about the racquet handle, it seems a bit larger than stated. I use an L3, 4 3/8" handle and the Bublik seems a bit larger than I'm used to. I don't know if this will cause any problems down the line. This is a fun and rewarding racquet to play with. You will be rewarded with spin and power with proper technique. Enjoy!

Diadem nailed the cosmetics on this one

Diadem nailed the cosmetics on this one. The PJ is great. Definitely a lot of spin generated with this racquet and also not shabby in the power. Best racquet in the Diadem line by a mile!

Great racquet!

Great racquet! Definitely a racquet I'd be willing to use along with my 23 Aero98's

Comfortable racquet compares to 2023 Aero 98 which was giving me wrist pain

Comfortable racquet compares to 2023 Aero 98 which was giving me wrist pain. Spin generation is good and power also, a little less than Aero 98 but adding some weights on 6 & 9 makes them very similar, although I like the lower twist weight without it. Feelwise it's dampened but in a good way, less crisp than Aero but not as muted as 2026 Vcore 98 so kind of sit in between, similar to Tecnifibre racquets which I like.
